Cria is the name for a baby camelid such as an alpaca, llama or vicuña. It is derived from the Spanish word cría, meaning "baby." Why is this Alpaca yarn so soft? SimpliCria is made with the finest 1% of all Alpaca Fleece. In our Peruvian mill, Alpaca is hand sorted two times. During the first sort, the top 10% of the fleece is set aside as Baby Alpaca (21-22.5 microns). After hand sorting the Baby Alpaca, the softest 10% is then designated as Super Baby Alpaca (19-20 microns).
